D. patient sneezing on a doctor
How do vaccines work?
A. They don’t
B. Vaccines use the body’s natural adaptive immune system to build up a resistance to a disease by creating antibodies before we are ever exposed to it giving us increased resistance or even complete immunity to the disease
C. vaccines give us the full disease, and your body will either fight it or not
D. I have no idea what a vaccine is
During a secondary exposure to a pathogen the immune system will:
A. React slowly
B. Produce few antibodies due to fatigue from the first infection
C. React more quickly and produce a greater number of antibodies
D. Act the same as the primary exposure

A. Fever
B. Mucus
C. Dilation
D. Inflammation

A. macrophage
B. pathogen
C. vaccine
D. flu
Widespread immunity that protects the population from the spread of disease is called
A. seropositivity
B. cross-reactivity
C. epidemic prophylaxis
D. herd immunity
Since we have our immune system to protect us from disease, why do we still need a vaccine?
A. Because some diseases are too severe for our immune system.
B. Because adaptive immunity takes days to weeks to initiate a response and sometimes it is too late.
C. Because some people are immune deficient or have weak immune systems.
D. All of the above
The green circle represents a/an
